Application filed llovember 25, 1911.

To all'whomi-z. may concern. g m to it known that I, GEORGE M. SCHUI'T, a citizen of the United States of Ameri a, and resident of tinc'innati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements'in Cans, of which the following a specification.

An object of this invention toproduee an in'iproved can or 'metal r; tacle, and: also an. improved method or process of malt ufaeturing the sai'ne. ()ne of the ditliculties ordinarily -'encouutered in the manufacture of large n tiil cans or receptacles,i tllat the .heat to which the cans are subjected-during. the galvanizing o} eration sets up inherent and unequal temp; at-ure strains in. the metal of the can, and often causes-the canto dis tort to such an extent,- that it is rendered uselessl- This 'diificulty is more likely to be encouuteredin the manufacture of large rec- Specification of Letters Patent.

tangular cans employed in refrigerating apparatus as the receptacles for the-water to l be frozen, than in the manufacture of other cans, since a sligl'it distortion of the metal forming the body portion of the can, .will' thereasy removal of the ice from the can.

One object of this invention is to produce a can particularly adapted to be used as a receptacle for water to be frozen iu tlhe inan ufacture; of ice, and also to produce an improved .method ofmanufacturing the can, which will prevent the objectionable distortion above referred to. This, together with other objects, I attain by means of a can embodying the features illustrated and described in this applicatiomand by adhering to the method of manufacturing cans, which is herein set forth.

In the drawings accompanying and forming a part of this application, Figure 1 a perspective View ofa can embodying my invention, and formed in accordance with the novel process or method of manufacture herein described. Fig 2- is afragmental plan view ofthe upper edge of the can shown in Fig, 1. Figs. 3 and e are fragmental sectional views of the can shown in Fig. 1, and respectively show the construction of the upper edge and at the bottom of i the can.

The can illustrated as an embodiment of my invention consists of a bony portion formed of corrugated sheet metal, and a base portion (3, which is preferably, but not neces- Patented Nov. '10, 1914.

'arily formed of sheet metal, andis provided with means, such as a flange 7, formed by. bending the edge of the metal blank, 10f, whichthe base is formed, for securing-the, baseto the'body portion. The bottorn-is; shown secured to the .body 5, by in ea'nsof rircts S, but it may be secured in place-by any suitable means, and, if desired, my be; I corrugated, like the body portion. of. the can. The corrugations of the body portion extend '65 parallel to the vertical axis of the can, that is, from the closed bottom to the open-top jot- The corrugations may ekten'diin 7Q; cans adapted to be employed as; receptacles- 3 for water to be frozen, the corrugationsmust :extend from the top 'to the bottom of the.

i can, so that the blocks ofice formed therein;

canbe removed therefrom withbut dilfi culty. In addition to this, the corrugations at the top and bottomof the caninust be-" spe-cially formed, so that there will be no reentrant or inwardly projecting'shouldcrs orlugs, which will prev-Lent the ice from -slip" 30 ping longitudinally. wt. oft-he. ca-n..' For these reasons. I. have so formed the corrugations that a flat riveting edge 9 isjfoi med at the top of the can, with its innersurface flushwith the bottom portions of the grciovcs, 35 formed on the inside of the can by the cor ingati ons, and a/flat rivetingedgeflO is termed at the bottom of the can, and is so located that its inner surface is flush with. the innermost portions or apexes of the Q ridges formed on the inside of the can by the corrugations. With this arrangement, the lower ends of the ridges on the ice formed in the can will taper off to a flat surface, and there will be no proi ecting SllOlllders on the block f ice, which will prevent it from being eas'igy removed from thecan. The. riveting flange 7 of the bottom (3 of the canv is shown located on .the outside of the v voting edge 10 of the body portion 5. "This, however, is 'not necessary, since the flange 7 Y may be located on the inside of the bodyportion, without de mentally affecting the l utility of the can.- The rivets 8 are'necessarily countersunk at their inner ends,'s0 thatthey will not-dorm projecting lugs, which will prevent. the removal of the ice. I have provided a reinforcing band 12 at the top of the can. which is shown secured on the outside. of the body portion, around the rivet- .ing edges 9 by means of rivets, which are rugations may extend'to the upper edge of -the can, or'that the riveting edges 9 may be "Q formed that the reinforcing bands 12 may 16. i i j Thelateral edges of the sheet metal formbe located on the inside of the upper edg'e'of the can, without obstructing the ends of'the grooves formed by the corrugations.

Lingerie body portion 5, are shown riveted togethenalong'a' line parallel to the vertical axis jof the can. Any convenient method may, howe\-'er, be employed for securing .theseedges together, which does not produce pro ecting lugs or shoplders on the in- Cans of the kind above 'I 1anily formed of sheet iron, and are made jaftr the sheets are galvanized. It is sideiof the can. I

described are ordi- "highlyqiesirable to subject the can to the galvanizing process after its parts have been.

assembled and secured together, since the Joints and the connections are all galvanized and the seamsare filled with zinc or other galvanizing metal employed, and a more perfect can is produced than is the case when the metal forming the can was first galvanized and then manufactured into a can. The heat to which the can must neces- -sarily be subjected during the galvanizing ;operation, is apt to, and often does,'cause "ythe metal of. which the rectangulambody -portion is formed, to expand unequal amounts and to thereby distort the sides of the can to'such an extent, that the can is rendered useless for the purpose for which it was intended;

While I have described my invention as applied to receptacles or molds for making ice, I desire it to be understood that receptacles embodying my invention may be otherwise utilized and that various changes and modifications, substitutions and omissions may be made by the apparatus illustrated, Without departing from the spirit and scope of my invention as set forth by the appended claims.

\Vhat I claim is:

1. An ice mold comprising a body portion having unobstructed longitudinally extending parallel grooves formed on the inside faces of the side portions thereof, and a bottom connecting ed e formed on the side portions thereof wit its inner surfaces located flush with the apexes of the ridges;

formed between said secured to said edge.

2. An ice mold having a rectangular body portion with longitudinally extending corrugations formed therein, a bottom 'connecting flange formed along the lower edge thereof, flush with the apexes of the corrugations on the inside of the can and a lip flange formed along the upper edge thereof,-

grooves, and a bottom flush with the apexes of the corrugations on 'tho outside body portion and a bottom secured to said bottom connecting flange.
